EXPLANATION OF COMPONENTS
AUTO-DECELERATION SWITCH
Auto-deceleration switch automatically lowers the engine
speed and turns on the function to reduce the fuel consumption
when the control levers are at NEUTRAL position.
Auto-deceleration pilot lamp is lit: Auto-deceleration ON
Auto-deceleration pilot lamp is not lit: Auto-deceleration OFF
Each time the switch is pressed, the auto-deceleration is
switched between ON and OFF.
Function of auto-deceleration
When the auto-deceleration function is enabled, if the work equipment lever and travel lever are returned to
NEUTRAL position, the engine speed will drop after approximately 4 seconds from the operating speed to the
idle speed.
As a result, fuel consumption can be reduced.
If any lever is operated in this condition, engine speed will return to the previous operating speed, and you can
perform the operation.
